What Is GPA?
GPA stands for Grade Point Average. It is a standardised numerical measure of academic performance used by schools, colleges, and universities — particularly in the United States, Canada, and many international institutions. Your GPA is calculated from the grades you earn in each course, weighted by how many credit hours (or units) each course carries.
A higher GPA reflects stronger academic performance. GPA is used for academic honours, scholarship eligibility, graduate school applications, and employment screening in some industries.
How GPA Is Calculated
GPA is calculated using a weighted average formula:
Each letter grade is assigned a grade point value. On the 4.0 scale: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0. You multiply each course's grade points by its credit hours, sum all those products, then divide by the total credit hours attempted.
GPA Calculation Example
Suppose you took three courses this semester:
| Course | Grade | Grade Points | Credit Hours | Quality Points |
|---|---|---|---|---|
| Mathematics | A | 4.0 | 3 | 12.0 |
| English | B | 3.0 | 3 | 9.0 |
| History | A− | 3.7 | 2 | 7.4 |
| Total | 8 | 28.4 |
GPA = 28.4 ÷ 8 = 3.55
GPA vs CGPA: What's the Difference?
GPA (Grade Point Average) refers to your average for a single term or semester. CGPA (Cumulative GPA) is your overall academic average across all completed semesters, weighted by credit hours. CGPA is what appears on transcripts and is used for graduation requirements, graduate admissions, and most academic evaluations.
4.0, 5.0, and 7.0 Grading Scales
Different countries and institutions use different GPA scales:
- 4.0 scale — the most common in the USA and Canada. An A earns 4.0 points.
- 5.0 scale — the standard in Nigerian universities. Grades are A (5), B (4), C (3), D (2), E (1) and F (0), with no plus or minus.
- 7.0 scale — used in many Australian universities. Grades are High Distinction (7), Distinction (6), Credit (5), Pass (4) and Fail.
This calculator supports all three scales. Select the scale that matches your institution before entering grades.
Important Disclaimer
GPA calculations are estimates. Your school, college, university, or admissions body may use a different grading policy, rounding convention, or treatment of failed and repeated courses. Always verify your official GPA through your institution's student portal or registrar.
Frequently Asked Questions
GPA (Grade Point Average) is calculated by multiplying each course's grade points by its credit hours, summing these products, then dividing by the total credit hours. For example: (A×3 + B×2) / 5 credit hours.
GPA refers to your grade point average for a single semester. CGPA (Cumulative GPA) is the overall average across all semesters, weighted by credit hours. CGPA gives a comprehensive picture of your academic performance.
On a 4.0 scale, a GPA of 3.5 or above is typically considered very good (Dean's List at many schools). A 3.0 is a B average. Many graduate programs require a minimum of 3.0.
The 5.0 scale, standard in Nigerian universities, has six grades with no plus or minus: A = 5, B = 4, C = 3, D = 2, E = 1 and F = 0. The 4.0 scale used in the US and Canada adds plus and minus grades (A- = 3.7, B+ = 3.3) and has no E. Select the 5.0 scale above to see the A–F options.
